Steve’s take

I-65 is how you get out of the Midwest and over to the Gulf or the Florida theme parks. From Chicago or Indianapolis, the natural play is I-65 south to either I-24/I-75 (Chattanooga, then Florida) or all the way to Mobile and pick up I-10 east. Lisa and I did the I-65 → I-24 → I-75 route a few years back and the Mammoth Cave detour was the unexpected highlight — it's right off the highway in Kentucky, the self-guided cave tour takes 90 minutes, and the kids talked about it for a month.

Nashville is on the corridor — easy lunch stop or worth-it overnight if you want to hit Broadway with the older kids.

Why families drive I-65

  • Most direct route from Indiana and Chicago to the Gulf
  • Mammoth Cave National Park is a 30-minute detour from the highway
  • Nashville lunch or overnight option
  • Lower traffic than I-75 or I-95

Clear sailing. One of the better days to drive this corridor.

Steve's take

Easy corridor most of the year. Louisville and Nashville have the only meaningful rush-hour traffic. Avoid the corridor during Kentucky Derby week (first Saturday in May) — Louisville is a parking lot. Bowling Green has manageable construction year-round.

Cost notes

I-65 itself is toll-free its entire length. Some optional toll bridges in Louisville. Gas is cheapest in Kentucky and Alabama. Hotels in Bowling Green KY $90–$110 (excellent value), Nashville $150–$250 (avoid downtown if budget-conscious), Birmingham $100–$130.

Where to overnight on I-65

  • Bowling Green, KY

    Workhorse overnight. Right off the highway, cheap chains, near Mammoth Cave.

  • Nashville, TN

    Splurge night. Stay in the Gulch or Midtown, walk to dinner.

  • Birmingham, AL

    Final stop before Mobile or Florida pickup.
